Welcome. Today we will explore database
systems designed for the internet of
things. This presentation will cover
storage solutions specifically tailored
for the unique challenges and demands of
IoT data. We will explore databases, the
internet of things and data
storage. The world of IoT presents
several data related
challenges. First, the massive volume of
data is generated continuously.
Second, heterogeneous data formats and
structures are involved. Third,
real-time processing requirements exist.
Fourth, resource constraints are present
on edge devices. And finally,
scalability and distribution present
their own
challenges. Consider the diagram showing
cloud storage, gateway, and various
devices. The connections between them
indicate the flow and storage of data,
There are several types of databases
available for internet of things. Let's
start with relational
databases. These databases use
structured data with a fixed schema and
support acid
transactions. You can perform complex
queries with SQL. However, they have
limited scalability for large volumes of
IoT data. Examples of relational
databases include Poster SQL, MySQL,
SQLite, and Timecale DB. Next are NoSQL
databases which have a flexible schema
for varied internet of things data. They
offer horizontal scalability, high write
throughput and better support for time
series data. Examples include MongoDB,
Cassandra, Influx DB and
Reddus. Beyond the traditional database
types, several specialized options cater
specifically to the needs of Internet of
Things applications.
Time series databases are optimized for
handling timestamp data points collected
at regular intervals from sensors and
devices. These are suited for sensor
data monitoring, performance metrics,
and environmental tracking. Edge
databases are lightweight databases
designed to run on edge devices with
limited resources, enabling local data
processing and storage. These are useful
for smart home devices, industrial
controllers, and offline first applications.
applications.
Stream processing systems process
continuous data streams in real time,
enabling immediate analysis and response
to data. These are helpful in real time
analytics, anomaly detection, and predictive
maintenance. Let's dive deeper into time
series databases for the internet of
things. They offer high-speed data
ingestion, timebased data organization,
efficient time range queries, data
compression and downsampling and
retention policies with time to live.
Some popular solutions include Influx
DB, Timecale DB, Prometheus and Amazon
time stream. Here is an Influx DB
example using
InfluxQL. First create a database for
Internet of Things sensor data. Then
insert temperature data points. Finally,
query the average temperature by
location. Let's take a closer look at
edge computing
databases. They offer a lightweight
footprint, offline first operation, low
latency access, energyefficient design,
and synchronization capabilities with
the cloud. Popular edge databases
include SQLite, Rox DB, Level DB, and
Pouch DB. Consider the diagram that
depicts an edgetocloud database
architecture. The diagram illustrates
how data flows from the edge devices
through the edge gateway to the cloud
databases. This setup helps in local
storage, local processing, and efficient
Stream processing for IoT data offers
real-time data analysis, a continuous
processing model, immediate anomaly
detection, dynamic data aggregation, and
pattern recognition in motion. Popular
stream processing systems include Apache
Kofka streams, Apache Flink, Apache
Spark streaming, and Amazon Web Services
Kinesis. This is a Kafka streams
example. First define a stream
processing topology.
Then create an input stream from
temperature sensors. Filter readings
above a certain threshold and send
alerts for high temperatures. Stream
processing is useful in industrial
equipment monitoring, connected vehicle
infrastructure. IoT systems pose several
challenges. One is data volume. IoT
systems can generate terabytes of data
daily from thousands or millions of
connected devices, overwhelming
traditional database systems. The
solutions here involve distributed
database architectures, data compression
techniques, automated data tearing
strategies, and edge filtering to reduce
cloud data. Another challenge is
performance and latency. IoT
applications often require real-time
data processing and low latency
responses, especially for critical
systems like industrial controls or
healthcare monitoring. Possible
solutions are in memory database
technologies, edge computing databases,
optimized indexing strategies, and
caching layers for frequent queries. The
final challenge is data heterogeneity.
IoT devices produce diverse data types
including structured metrics,
semistructured logs, unstructured text,
images, and video streams from various
sources. Solutions include multimodel
databases, schemalless NoSQL solutions,
data lakes with unified access, and
transformation. Here are a few best
practices for IoT databases.
One, design for scale from the
beginning. Two, implement data life
cycle management. Three, balance edge
and cloud processing. Four, prioritize
security and privacy. And five, optimize
for rightheavy workloads. Looking
forward, there are a few future trends
to keep an eye on. These are artificial
intelligence powered database
optimization for IoT workloads,
serverless database platforms for IoT,
blockchain integration for data
integrity, federated databases across
edge networks, and quantum computing for
complex IoT
